View current performance activity
We can view the current performance activity of a server using the Tivoli Performance Viewer in the administrative console.
Once monitoring is enabled, TPV monitors the performance activity of all servers on a node, which includes the associated application servers and the admin agent for the node being monitored. TPV enables administrators and programmers to monitor the current health of WAS. Because the collection and viewing of data occurs in the application server, performance may be affected.
To minimize performance impacts, monitor only those servers whose resources need to be optimized.
Monitor and Tuning | Performance Viewer | Current Activity
- Start monitoring the current activity of a server in either of two ways:
- Under Server, click the name of the server whose activity to monitor. Clicking on the name starts the monitoring for the server and displays the activity page for the server.
- Select the check box for the server whose activity you want to monitor, and click Start Monitoring.
A TPV console panel is displayed, providing a navigation tree on the left and a view of real-time data on the current performance activity of a server on the right.
- From the navigation tree, select the server activity data to view.
Option Description Advisor Use the Performance Advisor get advice on inefficient settings Sets Configure user and logging settings for TPV. These settings can affect the performance of the application server. Summary Reports View summary reports on servlets, EJBs, EJB methods, connections pools and thread pools in WAS. Performance Modules View performance modules that provide graphics and charts of various performance data on system resources such as CPU utilization, on WebSphere pools and queues such as database connection pools, and on customer application data such as servlet response time. In addition to providing a viewer for performance data, TPV enables you to view data for other products or customer applications that have implemented custom PMI.
What to do nextWhen you finish monitoring a server, select the server and click Stop Monitoring. TPV automatically stops monitoring a server if the browser window is closed or if the user logs out. When using Mozilla Firefox v3.5.16, the TPV graphical charts do not render correctly. When viewing performance data, you might see an empty graph or missing data, even though you selected counters to display in the chart. Use Firefox Version, 3.6.13 or higher, to resolve this problem.
